It is all highly subjective IMO.
For me ED never ruled anything. It was very promising before 2.1, with 2.1 it took wrong turn and at that point it was 100% clear to me that it is not the game i wanted to see. I am still playing X3, and at this point more than ED, and despite all the shortcomings and limitations of that game ED never got even close to what can be done there and how alive it feels. Basically the only good thing about ED (and the only thing that keeps me playing) is how good actually "flying spaceship" is done, including graphics, sound, cockpit, flight model etc...and even some of this things are getting worse with updates...
Eve, STO and such? Totally different games, they are fun too, in a way, and i played them too, but basically this are just another MMORPG-s with spaceships instead of elves and dwarfs, nothing to do with ED or X....
